BACKGROUND

People are increasingly interacting with computers and other electronicdevices in new and interesting ways. With the increased processingcapabilities, connectivity and location tracking, electronic deviceshave become widespread and used in many everyday activities. Forexample, people often use electronic devices to search for products,watch videos, listen to music, research, shop for both digital andphysical products (“e-commerce”), and receive news, just to name a few.Other uses include communicating with social communities, friends andfamily, photography, and many others.

Sellers in the e-commerce market typically establish a website that maybe visited by users to browse various web pages within the website thatinclude product information relating to products offered for sale by theseller. A user may typically obtain product details, product reviewsposted by other users, and/or purchase the item from the seller of theproduct. Upon purchase of the product, the seller will package and shipthe item to a user specified delivery destination.

DETAILED DESCRIPTION

This disclosure describes systems and methods for matching user providedimages that include representations of items with sellers of thoseitems. A management service, as described herein, may provide a web sitewhere users can post images, view images, share images, correspond withother users, etc. In the implementations described herein, themanagement service may identify items represented in the images anddetermine one or more sellers that offer those items for sale. Forexample, a seller of items may provide an item catalog to the managementservice that identifies items offered for sale by the seller that may bepurchased by users from the seller. The item catalog may identify theitem, a source location identifier, such as Uniform Resource Locator(“URL”) of a web page of the seller's website from which the item may beviewed and/or purchased from the seller, an image of the item, iteminformation, image information, etc.

The management service may use the information from the item catalogprovided by the seller to determine if any of the images accessible byusers of the management service include representations of items offeredfor sale by the seller. For example, in some instances, users of themanagement service may post an image to the management service that wasobtained from another web page, such as a web page of the seller'swebsite. In such an instance, the posted image may include imageinformation, also known as metadata, which includes the URL from whichthe image was obtained. If the URL of the image provided by the usercorresponds with a URL included in the item catalog, it may bedetermined that the image provided by the user to the management serviceincludes a representation of an item available for purchase from theseller and the user provided image is associated with the item and/orthe seller of the item.

In another example, if the image provided by the user does not include aURL, or the URL included in the image information does not correspondwith a URL from the item catalog, the image may be processed using oneor more image processing algorithms to detect an item represented in theimage. The processed image may then be compared with images and/or imageinformation included in the item catalog provided by the seller todetermine if an item offered for sale by the seller is represented inthe image. If it is determined that an item offered for sale by theseller is represented in the image provided by the user, the userprovided image is associated with the item and/or the seller of theitem.

When the user or another user of the management service requests to viewthe user provided image that has been determined to include arepresentation of an item offered for sale by the seller, a purchasecontrol is presented with the user provided image. In addition, sellerinformation that identifies the seller and/or the item may likewise bepresented with the presentation of the user provided image. The purchasecontrol is selectable by the user viewing the image to obtain variantinformation about the item represented in the image and/or to purchasethe item represented in the image from the seller. Item “variantinformation,” as used herein, is additional information about the itemand/or the sale of the item. For example, item variant information mayinclude the quantity of the item available for sale by the seller, theprice of the item, a size of the item, a color of the item, a shippingcost for shipping the item, a shipping time, and/or other information.

If a user requests to purchase an item represented in a user providedimage from a seller that has been determined to offer the representeditem for sale, the management service facilitates the purchase betweenthe user and the seller. For example, the management service may providean item identifier, item information (e.g., selected variants), useridentifier, etc. In some implementations, the management service maylikewise facilitate payment by the user for the item, such as through athird party payment processor. Alternatively, payment information may beprovided to the seller for processing of payment for the item. Finally,purchase of the item is completed and the seller may ship the item tothe user.

An “item” may be anything that can be represented and offered for sale.For example, an item may be a physical good (clothing, hardware,paintings, etc.), a digital item (e.g., audio, video, image), a service(e.g., landscaping, banking, house painting).

FIG. 1 is a pictorial diagram of an illustrative environment thatincludes users 101, such as users 101(1), 101(2)-101(N), a server system100 that includes one or more server computers 100(1), 100(2)-100(N),one or more client devices 104, such as client device 104(1), 104(2),104(3)-104(N), and one or more sellers 106, such as a Seller A 106(1),Seller B 106(2)-Seller C 106(N) communicatively connected via a network108. As will be appreciated, any number and/or type of server systems100, client devices 104 and/or sellers 106 may be included in theenvironment, and those illustrated in FIG. 1 are only exemplary.Likewise, any number of users 101 may be included in the environment.For purposes of this discussion, the term “user” will be used herein torefer to an individual interacting with the management service 110(discussed below) to post or otherwise provide images, view images,share images, correspond with other users, purchase items represented inviewed images, etc.

The network 108 may include a local area network, a wide area network,such as a public switched telephone network (PSTN), a cable televisionnetwork, a satellite network, a collection of networks, a publicInternet protocol network, a private Internet protocol network, or acombination thereof. Moreover, the network 108 may be wired, wireless,or a combination of the two. The server system 100 may also include amappings data store 111, an image data store 113, an item catalog datastore 115, and/or a user profile data store 117. As discussed furtherbelow, the data stores may include lists, arrays, databases, and otherdata structures used to provide storage and retrieval of data. Likewise,while the disclosure describes multiple data stores, in someimplementations, the data stores may be configured as a single datastore or multiple data stores.

The mappings data store 111, image data store 113, item catalog datastore 115, and user profile data store 117 may be integrated with theserver system 100 or otherwise communicatively coupled with the serversystem 100. For example, one or more of the mappings data store 111,image data store 113, item catalog data store 115, and/or user profiledata store 117 may be located at a remote computing resource (not shown)and communicatively coupled with the server system 100. In someimplementations, the mappings data store 111, image data store 113, itemcatalog data store 115, and/or user profile data store 117 may includeone or more CD-RW/DVD-RW drives, hard disk drives, tape drives, or otherstorage devices that are utilized to store digital content andinformation. The server system 100, separately or together with themappings data store 111, image data store 113, item catalog data store115, and/or user profile data store 117, may provide a managementservice 110 that facilitates user 101 postings of images, viewing ofimages, sharing of images, corresponding with other users, viewing ofitem variant information for items represented in images, and the like.Likewise, the management service 110 may facilitate the purchase by auser of a user provided item represented in an image from a determinedseller of the item.

The server system 100 may also be configured to exchange informationwith one or more sellers 106. The sellers 106 may include any type ofentity and/or individual(s) that offers items for sale. For example,sellers 106 may include e-commerce websites that sells and deliversitems, a service offering, a traditional retail or wholesale store, etc.

In some implementations, the sellers 106 may interact with themanagement service 110 and provide and/or update an item catalog listingitems offered for sale by the seller. The item catalog may include iteminformation about each item offered for sale by the seller. For example,the item information may include a name of the item, a price of theitem, a URL for the seller's web page from which the item may be viewedand/or purchased from the seller, a geographic location of the seller,an advertising amount the seller is willing to pay to advertise the itemand/or have a user provided image associated with the item, etc. Forexample, a seller may offer for sale thousands of items via their owne-commerce website and each of those items may be associated with orrepresented on one or more web pages of the seller's website. The seller106 may provide to the management service 110 an item catalog listingone, some, or all of the items that the seller offers for sale. Asdiscussed further below, the management service 110 may store the sellerprovided item catalog in the item catalog data store 115 and determineif any of the user provided images maintained in the image data store113 include a representation of an item listed in the item catalogprovided by the seller. Images maintained in the image data store 113that include a representation of an item identified by the seller in theitem catalog are associated with the item and/or the seller. Theassociation is maintained in the mappings data store 111.

The advertising amount may identify an amount the seller is willing topay to promote the item, to have the item associated with user providedimages that include representations of the item, and the like. In someimplementations, the advertising amount may be based on the number ofviews or impressions the item receives by users of the managementservice. In other implementations, the advertising amount may be for adefined period of time, etc. In implementations when more than oneseller offers a same or similar item for sale, the advertising amountmay be utilized as a factor in determining which seller(s) is associatedwith a user provided image that includes a representation of the item.

Sellers 106 may also periodically update the provided item catalog byidentifying additional items that the seller offers for sale, removingitems from the item catalog, by providing updated variant informationfor items identified in the item catalog and/or by altering theadvertising amount for the item. Those updates are reflected in the itemcatalog data store 115 and may be used by the management service 110when presenting images to users.

Returning to FIG. 1, client devices 104 may include personal computers,tablet computers, eBook reader devices, laptop computers, desktopcomputers, netbooks, personal digital assistants (PDA), portable gamingdevices, wireless communication devices, such as smart phones or mobilehandsets, set-top-boxes, game consoles, cameras, audiorecorders/players, or any combination thereof. As will be described withregard to the implementations shown herein, the server system 100 isconfigured to exchange data and information, including information aboutusers, images, sellers, items, item variants, and other like informationwith client devices 104. For example, the management service 110 mayinteract via the server system 100 to present images to a user 101,present item variant information to a user 101, facilitate purchase ofan item between a user and a seller of the item, and the like.

Likewise, a user 101 may interact with the management service 110, via aclient device 104, to provide images, view images, share images,correspond with other users, initiate a purchase of an item from aseller of the item, etc. As described herein, a user that provides animage that includes a representation of an item is a different person orentity that is determined to be a seller of the item represented in theimage.

The mappings data store 111 stores information about the associationsbetween items represented in user provided images and items offered forsale by sellers. For example, an item may be determined to berepresented in a user provided image that is available for sale (listedin an item catalog) from three different sellers. In such an example,the mappings data store 111 will maintain an association between theuser provided image, which is maintained in the image data store 113,and the corresponding item listed in each of the seller's provided itemcatalogs.

The user profile data store 117 stores information about users 101 ofthe management service 110. Any type of information may be stored in theuser profile data store 117. For example, user profile information, suchas attributes, name, address, gender, browse history, purchase history,billing information, shipping information, purchasing information,social networks and/or friends with which the user 101 interacts, andthe like, may be stored in the user profile data store 117. User profileinformation may be provided directly by users 101 and/or collected fromusers 101 of the client devices 104 when interacting with the managementservice 110 (e.g., clickstream data as the user explores the managementservice 110), when posting, viewing, and/or sharing images, whenfacilitating a purchase between the user and a seller, etc. In someimplementations, users of the management service 110 may choose to limitthe amount of information included in their user profile, to limitaccess to their user profile information and/or to limit whatinformation is shared, if any, from their user profile information. Theuser profile information maintained in the user profile data store 117may be used by the management service 110 to facilitate a purchase of anitem by a user from a seller.

In addition to maintaining information about mappings, item catalogs,images, and users, the management service 110 may provide useinformation back to the users 101 and/or the sellers 106. For example,the management service 110, through communication between the serversystem 100 and a client device 104, may provide use and/or purchaseinformation (e.g., purchase history) back to a user 101. Suchinformation may include an identification of images recently viewed,provided or shared, an identification of others that have viewed imagesposted by the user, purchases of items made by the user, and the like.Likewise, the management service 110, through communication between theserver system 100 and the sellers 106, may provide information to thesellers 106. Such information may include analytics about items offeredfor sale by the seller, such as how many user provided images include arepresentation of each item, purchase history for items, etc.

FIGS. 2-3 are block diagrams of an example implementation for matching aseller 206 of an item with a user provided representation of the item,according to an implementation. The example implementation begins with aseller 206 providing an item catalog that identifies one or more itemsoffered for sale by the seller 206. The item catalog is delivered overthe network 208 to the management service 210 and the management service210 stores the item catalog in an item catalog data store 215. Themanagement service 210, upon receiving an item catalog from the seller206, processes user provided images that are stored in the image datastore 213, referred to as stored images, to determine if any of thestored images include a representation of an item identified in the itemcatalog as an item offered for sale by the user.

Processing of the stored images may be incrementally performed. Forexample, an initial processing may include comparing a source locationidentifier, such as a URL, listed in the item catalog for an item, withsource location identifier included in the image information of thestored images to determine if any of the source location identifiers arethe same or similar. For example, if the source location identifiers areURLs, it may be determined that a source location identifier of anexisting image is the same as a source location identifier listed in theitem catalog if the two URLs are the same. Likewise, it may bedetermined that a source location identifier of a stored image issimilar to a source location identifier listed in the item catalog ifthe two URLs have a same domain address (are from the same website ordomain).

If the source location identifiers are the same, it may be determinedthat the stored image includes a representation of an item offered forsale by the seller. If the stored image includes a source locationidentifier that is similar to that of a source location identifierincluded in the item catalog, the stored image may also be processedusing one or more image processing algorithms to determine if the storedimage is similar to the image or image information included in the itemcatalog that corresponds with the similar source location identifier.For example, a hash value may be determined for the stored image andcompared to a hash value included in the item catalog. Alternatively,one or more image processing algorithms, such as an edge detectionalgorithm, object detection algorithm, etc., may be utilized todetermine features of the stored image, which may be represented asfeature vectors. Images provided with the item catalog may likewise beprocessed to generate feature vectors (or feature vectors may beprovided with the item catalog). The feature vectors of a stored imagemay then be compared with feature vectors for the item(s) identified inthe item catalog with the similar source location identifier and, if thefeature vectors are similar, it may be determined that the stored imageincludes a representation of an item offered for sale by the seller. Insome implementations, the additional processing of the images maylikewise be performed for images with a same source location identifier.

A source location identifier may be any location, physical or virtual,that is associated with an item and/or any other identifier that can beused to identify the item. For example, as discussed above, a sourcelocation identifier may be URL of a webpage at which informationrelating to the item may be obtained. In another implementations, thesource location identifier may include physical coordinates of one ormore physical locations (e.g., physical stores of the seller) where theitem may be viewed and/or purchased. In such an implementation, a userprovided image may include location information, such as globalpositioning system (GPS) coordinates, that are compared with thecoordinates included in the item catalog. In still otherimplementations, the source location identifier may include a universalproduct code (UPC), barcode, bokode, etc. that is associated with theitem.

In some implementations, stored images that are not matched to an itemof the item catalog as part of the initial processing may be furtherprocessed. For example, using the feature vectors for the processedstored image, it may be determined if an item is represented in theimage and, if so, a category for the item may be determined. Forexample, the management service may maintain a list of item categoriesand corresponding feature vectors that are representative of itemsassociated with the item category. Item categories may be any type ofclassification or categorization of items. For example, item categoriesmay include shoes, shirts, bags, sporting equipment, clothing, hats,cars, etc. For each item category, feature vectors, colors, shapes,and/or other characteristics of items associated with that category aremaintained and may be used to compare with feature vectors and/or otherinformation of the stored image. If there is a similarity between thefeature vectors and/or other information associated with the itemcategory and the feature vectors and/or other information of the storedimage, the stored image may be associated with that item category.

Likewise, the seller and/or items identified in the item catalog asoffered for sale by the seller may also be associated with an itemcategory. Associating items identified by a seller as associated with acategory may be done in a similar manner to that discussed above withrespect to associating a stored image with a category. Alternatively, orin addition thereto, the seller may identify the category for the item,for example, by identifying an item category for each item listed in theitem catalog.

Based on the category determined for the stored image and the categoriesassociated with the sellers 206 and/or items offered for sale bysellers, it is determined whether the stored image potentially includesa representation of an item listed in the provided item catalog. Forexample, if the item category determined for the stored imagecorresponds to an item category associated with the seller and/or theitem catalog provided by the seller, it may be determined that thestored image potentially includes a representation of an item offeredfor sale by the seller. If the stored image does include arepresentation of an item that may be listed in the item catalog,additional processing may be performed to determine the item representedin the image. The additional processing may include additional analysisof the stored image and/or comparison of the feature vectors and/orother image information between the stored image and items of the itemcatalog associated with the same item category. In another example, thestored image may be manually reviewed by a human and compared to itemslisted in the item catalog having the same item category to determine ifthe item represented in the image corresponds to an item listed in theitem catalog. The human may be an employee of the management service210, an independent reviewer, a user (or group of users) of themanagement service 210, a representative or employee of the seller 206,etc.

If it is determined that a stored image includes a representation of anitem listed in the item catalog provided by a seller 206, the managementservice establishes an association between the item listed in the itemcatalog and the stored image and stores the association in the mappingsdata store 211. Likewise, the management service may establish anassociation between the stored image and the seller 206 and maintainthat association in the mappings data store 211. As discussed furtherbelow, when a user requests to view a stored image, the managementservice 210 determines the association between the stored image and theitem offered for sale by the seller and presents seller informationand/or a purchase control with the presentation of the item.

Turning now to FIG. 3, a user 301 may also provide an image that may bematched with an item offered for sale by a seller. In this example, theuser 301, using a client device 304, provides an image to the managementservice 310 via the network 308. The management service, upon receivingthe image stores the image in the image data store 313, processes theprovided image, and compares the processed image with the itemsidentified in the item catalog data store 315 to determine if the userprovided image includes a representation of an item offered for sale bya seller. Processing of the user provided image may be performed in asimilar incremental manner as that discussed above with respect to FIG.2. For example, a source location identifier of the user provided imagemay be compared with source location identifiers maintained in the itemcatalog data store 315, the user provided image may be processed togenerate feature vectors that are compared with feature vectors foritems identified in the item catalog data store 315, image informationassociated with the user provided image may be compared with imageinformation from the item catalog data store 315, etc.

If the user provided image is determined to include a representation ofan item listed in the item catalog data store 315, the user providedimage is associated with the item and/or the seller that offers the itemfor sale and the association is stored in the mappings data store.

FIGS. 4-5 are block diagrams of an example implementation offacilitating a purchase of a represented item by a user, according to animplementation. Turning first to FIG. 4, the example implementationbegins with a user 401 requesting, through a client device 404, to viewan image that was provided by a user (the user 401 or any other user) tothe management service 410 and stored in the image data store 413. Therequest is sent from the client device 404 to the management service 410through a network 408. The management service 410, upon receiving theuser's request, queries the mappings data store 411 to determine anyassociations between the requested image and items offered for sale by aseller. If an association exists between the image requested by the userand an item offered for sale by a seller, as identified in the itemcatalog data store 415, the management service 410 provides therequested image and a purchase control that is presented to the user. Asdiscussed further below, the purchase control is selectable by the userto obtain additional details about the item represented in the requestedimage and/or to initiate a purchase of the item from a seller thatoffers the item for sale. In some implementations, the managementservice 410 may also provide seller information identifying the sellerof the item represented in the image.

In addition to providing the image and purchase control for presentationto the user 401, the management service 410 may also send a request tothe seller 406 for item variants related to the item represented in theimage that is available for purchase from the seller 406. The seller406, in response to receiving the request for item variants, may providethe current item variants for the item represented in the image that isavailable for purchase from the seller 406. In other implementations,rather than, or in addition to the management service 410 sending arequest to the seller 406, the seller 406 may periodically send itemvariant update information to the management service 410. For example,sellers 406 may specify update intervals (e.g., every hour, every day,weekly) and send item catalog and/or item variant updates to themanagement service that are maintained and used by the managementservice 410. In some implementations, the sellers 406 may be configuredto send item variant updates to the management service 410 when an itemvariant changes (e.g., price changes, quantity available changes). Insuch implementations, rather than the management service 410 sending arequest to the seller 406 for item variant information, the managementservice 410 may utilize the previously provided and stored item variantinformation for the item represented in the requested image.

Turning now to FIG. 5, if a user 501 selects or otherwise activates thepurchase control that was provided with the image, the request is sentto the management service 510. For example, the requested image andcorresponding purchase control may be sent by the management service 510to the client device 504, via the network 508, and presented to the user501 on a display of the client device 504. If the user selects thepurchase control, the request is sent by the client device 504, via thenetwork 508, to the management service 510.

In response to receiving the request, the management service 510 sendsto the client device 504 item variant information corresponding to theitem represented in the image and associated with the selected purchasecontrol. In some implementations, the item variant information may besent with another image(s) of the item, additional details about theseller and/or the sale of the item.

If the seller selects to purchase the item, as illustrated in FIG. 5,the purchase request is sent from the client device 504 to themanagement service 510 and the management service 510 facilitates apurchase of the item between the seller 506 of the item and the user501. In some implementations, the purchase of the item may be completedwithout the user 501 having to be redirected to the seller's website.For example, the management service may facilitate a payment (e.g., viaa third party payment processor) by the user for the item on behalf ofthe seller and provide the seller with a payment confirmation. Inaddition to the payment confirmation, the management service 510 mayprovide the seller with any item variants selected by the user (e.g.,size, color, shipping option), a delivery destination specified by theuser, etc. In other implementations, payment credentials of the user maybe provided by the management service 510 to the seller 506 forprocessing and order purchase completion. The payment credentials,delivery details, and/or other user related information may be providedby the user 501 to the management service 510 and/or maintained in theuser profile data store 517.

The seller 506, upon receiving purchase confirmation or completing thepurchase, initiates delivery of the item to the user. For example, ifthe item is a physical good, the seller 506 may cause the item to bedelivered to a user specified delivery location. Likewise, if the itemis a digital good, the item may be transmitted from the seller to theuser 501, for example, via the network 508. The management service 510may provide a confirmation message to the user 501 that the purchase ofthe item from the seller 506 has been completed.

As described, the implementations provide the ability to determine itemsrepresented in user provided images and match those items with a sellerthat offers the item for sale. While the examples described herein referto a single seller as offering the item for sale, in otherimplementations, an item represented in a user provided image may beavailable for sale from multiple sellers. For example, if the itemrepresented in the image is a sports shoe, that item may be availablefrom multiple different sellers of sports shoes. In such animplementation, the user provided image of the item may be associatedwith each of the sellers and a mapping maintained in the mappings datastore maintained by the management service. In some implementations, asingle seller may be associated with the purchase control when the userprovided image and the corresponding purchase control are sent to arequesting user. The single seller may be randomly selected, selectedbased on price, selected based on the user's past purchase history, thelocation of the user and the seller, and/or any other factor.Alternatively, the user may be provided a list of sellers uponactivation of the purchase control.

In addition to the management service determining multiple sellers foran item represented in an image, in some implementations, multiple itemsmay be represented in a single user provided image. In such instances,the image may be segmented based on the various positions of therepresented items, sellers determined for the different items, anddifferent purchase controls presented with each of those items.

For example, referring to FIG. 6, illustrated is a representation of asegmented user provided image that includes a plurality of items offeredfor sale by different sellers, according to an implementation. An image,such as image 600, may be segmented using image segmentation techniques.For example, a background of the image may be determined (e.g., based onout of focus regions and/or similar colors) and removed from processing.Likewise, six objects have been identified and the image segmented intosix different regions. Specifically, a body object 602, a head object604, a shirt object 606, a pants object 608, a bags object 610, and ashoes object 612. As part of the segmenting, the root object, in thisexample the body object 602, was determined and the location of otherobjects 604-612 considered when identifying those other objects.Segmentation of images is described in further detail in U.S. patentapplication Ser. No. 14/279,871 entitled “Image Based Search,” which isherein incorporated by reference in its entirety.

In other implementations, an image may be segmented using othersegmentation and identification techniques. For example, images may besegmented using crowd sourcing techniques. For example, as users view animage, they may select regions of the image that include objects and theimage may be segmented based on the location of objects within theimage. As more users identify objects within images, the confidence ofthe identity of those objects increases. Based on the user providedsegmentation and identification, the objects within the image can beidentified and a determination made as to whether the object is an itemoffered for sale by a seller.

For example, each segment may be processed to generate feature vectorsfor the item represented in the segment and those feature vectors may becompared with feature vectors associated with items identified in theitem catalog data store. Alternatively, or in addition thereto, thesegments of the image may be processed and the item classified into oneor more categories. For example, the shirt object 606 of the image 600may be processed to detect the object (shirt) represented in the segmentthat contains the shirt object 606 and the segment may be associatedwith a category representative of shirts (or another relevant category).As discussed above, the representation of the object (shirt) may becompared with items offered for sale by sellers associated with thecategory shirts and/or compared with items offered for sale that areassociated with the category shirts to determine if the objectrepresented in the segment of the image corresponds with an item offeredfor sale by a seller. This processing may be done for each object and/orsegment of the image to determine items represented in the image thatare offered for sale by one or more sellers.

FIG. 7 is a representation of a segmented image 700 presented on adisplay of a client device 704 with purchase controls associated withobjects of the image that are determined to be items offered for sale byone or more sellers, according to an implementation. For each itemdetermined in the segmented image to be available for purchase from oneor more sellers, a purchase control may be presented near the determineditem that is selectable by the user. In this example, a shirt 706 hasbeen determined in a first segment 705 of the image 700 and a purchasecontrol 726 is presented near the presentation of the shirt. Similarly,a bag 710 has been determined in a second segment 709 of the image and apurchase control 720 is presented near the presentation of the bag. Apair of pants 708 has been determined in a third segment 707 of theimage 700 and a purchase control 728 is presented near the presentationof the pants 708. Finally, a pair of shoes 712 has been determined in afourth segment 711 of the image 700 and a purchase control 722 ispresented near the presentation of the shoes 712.

While the majority of the segments of the image 700 have been determinedto include a representation of an item offered for sale by a seller, thesegment 703 that includes the object of a person's head is determined tonot include an item that is offered for sale by the seller. Because theobject (person's head) represented in the segment 703 is determined tonot be an item offered for sale by a seller, a purchase control is notpresented near the presentation of that object.

A user may view the image 700 on the client device 704 and selectivelyinteract with one or more of the purchase controls to obtain additionaldetails about an item associated with the purchase control. For example,FIG. 8 is a representation of an item and item variants for the shirtitem, according to an implementation. The information 800 presented onthe display of the client device 804 is generated in response to theuser selecting the purchase control 726 (FIG. 7) associated with theshirt item. In this example, upon selection of the purchase control 726,an additional view 810 of the shirt item is presented to the user alongwith a name 806 of the seller of the item, in this example Seller A,from which the item may be purchased. A name of the item “Summer CasualShirt For Her” 808 may also be included in the presented information800. The management service, as discussed above, may also obtain andprovide item variant information 812, such as a size, fit, color,shipping method, and/or quantity of the shirt. The user may alter orselect item variant information by, for example, interacting with thepresentations of the item variant information. In addition, a user mayalso be presented with purchase and/or shipping information 814 that iscurrently associated with the user of the client device 804 that will beused by the management service to facilitate a purchase of the item ifthe user selects the “Buy Now” control 816. A user may alter thepurchase and/or shipping information 814 by selecting the “Edit” control818 and providing or selecting alternative information. Any type or formof payment method may be used with the implementations discussed herein.For example, the user profile maintained by the management service thatis associated with the user may include credit card information, asillustrated, that is used to facilitate a purchase between the user andthe seller of the item. In other implementations, other forms ofpayment, such as bank transfers, e-commerce payment processors, etc. maylikewise be utilized.

In some implementations, a discount code 819 or other promotion may beassociated with the item represented in the additional view 810. Forexample, if Seller A 806 is offering a promotion for the item that isreceived if a discount code 819 is provided as part of the checkoutprocess, the discount code 819 may be automatically identified andincluded in the information 800 presented on the display of the clientdevice 804. In some implementations, the discount code 819 is providedby the seller as an item variant for the item. In other implementations,a user may alter, update or provide a discount code 819 by selecting thediscount code 819 and providing such information.

The additional view 810 of the item may be in the form of a digitalstill image, a video file, an animated .gif file, etc. For example, theadditional view 810 may include a presentation of an animated .gif filethat can be manipulated by a user to alter a presented view of the item.For example, if the client device 804 includes a touch-based display, auser may manipulate or control the presentation of the .gif file bymoving their finger on the touch-based display to obtain different viewsof the presented item. In one implementation, the user may control thepresentation of the image and rotate the image to obtain front, back,side and/or other views of the image, effectively providing a 360 degreeview of the image.

In some implementations, a user may view and/or provide comments,reviews, ratings, and/or other information related to the itemrepresented in the additional view 810. In some implementations, a usermay also be presented with an identification of related items oftenviewed or purchased with the item represented in the additional view810. A related item is an item that is often purchased with the item orview by users when viewing the item represented in the additional view810. For example, if other users of the management service oftenpurchase the item “Summer Causal Shirt For Her” from Seller A and alsopurchase a pair of matching shorts, the information 800 may alsoidentify the pair of matching shorts to the user as an item that isoften purchased with the item represented in the additional view 810.The user may obtain additional information about the pair of matchingshorts by selecting the identified pair of matching shorts.

If a user selects the “Buy Now” control 816, the management servicefacilitates a purchase of the item between the user and the seller.Facilitating purchase of the item is discussed further below withrespect to FIG. 13. In addition to facilitating purchase, the managementservice may also send a confirmation message to the user, as illustratedin FIG. 9. In this example, the management service sends to the clientdevice 904 a confirmation message 902 identifying that the seller of theitem received the order from the user for the item and that the sellerwill send the user a confirmation email.

FIG. 10 illustrates an example process 1000 for matching sellers withitems, according to an implementation. The example process 1000 and eachof the other processes described herein are illustrated as a collectionof blocks in a logical flow graph. Some of the blocks representoperations that can be implemented in hardware, software, or acombination thereof. In the context of software, the blocks representcomputer-executable instructions stored on one or more computer-readablemedia that, when executed by one or more processors, perform the recitedoperations. Generally, computer-executable instructions includeroutines, programs, objects, components, data structures, and the likethat perform particular functions or implement particular abstract datatypes.

The computer-readable media may include non-transitory computer-readablestorage media, which may include hard drives, floppy diskettes, opticaldisks, CD-ROMs, DVDs, read-only memories (ROMs), random access memories(RAMs), EPROMs, EEPROMs, flash memory, magnetic or optical cards,solid-state memory devices, or other types of storage media suitable forstoring electronic instructions. In addition, in some implementations,the computer-readable media may include a transitory computer-readablesignal (in compressed or uncompressed form). Examples ofcomputer-readable signals, whether modulated using a carrier or not,include, but are not limited to, signals that a computer system hostingor running a computer program can be configured to access, includingsignals downloaded or uploaded through the Internet or other networks.Finally, the order in which the operations are described is not intendedto be construed as a limitation, and any number of the describedoperations can be combined in any order and/or in parallel to implementthe process. Likewise, additional or fewer operations than thosedescribed may be utilized with the various implementations describedherein.

The example process 1000 begins by determining if there is a sourcelocation identifier, such as a URL, GPS coordinates, barcode, etc.,included in the image information of a user provided image, as in 1002.As discussed above, a user provided image may be already stored in animage data store of the management service or may be provided to themanagement service by the user. The user provided image may be any imageor representation of an object that is provided by the user to themanagement service. For example, the user provided image may be an imageobtained with an image capture device of a user's client device, animage copied from another website, an image from an electronic message,etc.

An image may include a source location identifier, such as a URL, if theimage is obtained from another location (e.g., a website) on a network,such as the Internet. In another example, the source location identifiermay identify a physical location at which the image was captured by animage capture device (camera). For example, when a camera obtains animage, it may include in the image information the GPS coordinates(latitude and longitude) identifying the position of the image capturedevice when the image was obtained.

If it is determined that the user provided image does not include asource location identifier, the example process 1000 proceeds to theexample process 1100 discussed below with respect to FIG. 11. However,if it is determined that the user provided images does include a sourcelocation identifier, the source location identifier of the user providedimage is compared to source location identifiers maintained in the itemcatalog data store, as in 1004. As discussed above, the item catalogdata store maintains a list of items offered for sale by one or moresellers. As the source location identifiers are compared, adetermination is made as to whether the source location identifier ofthe user provided image matches a source location identifier of an itemidentified in the item catalog, as in 1006.

If it is determined that the source location identifier of the userprovided image does not match any of the source location identifiers ofthe items in the item catalog data store, the example process 1000proceeds to the example process 1100 discussed below with respect toFIG. 11. If it is determined that the source location identifier of theuser provided image does match a source location identifier of an itemin the item catalog data store, the user provided image is associatedwith the corresponding item from the item catalog data store and/or theseller that offers the item for sale, as in 1008. This association ismaintained in the mapping data store by the management service.

Based on the association between the user provided image and the itemidentified in the item catalog data store and/or the seller of the item,each time the user provided image is presented to a user, such as when auser requests to view the user provided image, the presentation of theimage will include a purchase control and/or seller information, as in1010. The purchase control, as discussed above, may be selected by theuser to obtain additional information about the item represented in theuser provided image and/or to initiate a purchase of the item. Theseller information identifies a seller of the item represented in theimage. If multiple sellers are associated with the item represented inthe image, the seller information may identify one of the sellers, aseller determined based on a provided advertising amount for the item,multiple sellers, provide an indication that more than one seller isoffering the item represented in the user provided image for sale, etc.A user requesting to view the user provided image may be the user thatprovided the image, or any other user of the management service.

While the example illustrated in FIG. 10 describes matching a userprovided image with a seller if the source location identifier of theuser provided image matches the source location identifier of an itemlisted in the item catalog data store, in some implementations,additional analysis may be performed before the user provided image isdetermined to include a representation of the item offered for sale bythe seller. For example, the user provided image may be processed todetermine if the image is similar to or matches the image or the imageinformation included with the item identified in the item catalog ashaving a matching source location identifier. In other implementations,additional image information, such as a creation date, file size, hashvalue, color histogram, etc., may be compared to obtain additionalconfirmation that the user provided image includes a representation ofthe item offered for sale by the seller. In some implementations, all ora portion of FIG. 11 may be performed in conjunction with the exampleprocess 1000.

FIG. 11 illustrates an example process 1100 for processing a userprovided image to match an item represented in the image with a sellerof the item, according to an implementation. The example process 1100begins by receiving the image from a user, as in 1102. The receivedimage is then processed using one or more image processing algorithms,such as edge detection, object detection, grey scale analysis, etc., todetermine objects represented in the image, as in 1104. In someimplementations, feature vectors representative of the image and/orobjects within the image may also be generated.

In addition to processing the image, image information such as sourcelocation identifier, comments added by the user that provided the image,comments added by users that viewed and/or shared the image, the time,date and/or location associated with the image, etc., may also beconsidered, as in 1106. Based on the processed image and the imageinformation, a determination is made as to whether an item category canbe determined for an object represented in the image, as in 1108. Insome implementations, the management service may maintain a list of itemcategories for items that are offered for sale by different sellers.Each item category may include one or more item characteristics, such asa description, representative images of items associated with the itemcategory, representative shapes, sizes and/or colors of items that maybe associated with the item category, etc. Likewise, a seller may beassociated with an item category based on the types of items that theseller offers for sale. Likewise, items offered for sale may beassociated with one or more item categories based on the item type.

In determining if the object represented in the user provided image maybe associated with an item category, the processed image and/or imageinformation is compared with the characteristics of each item categoryto determine if the object represented in the image is similar to anitem category. For example, the size, shape and/or color of thedetermined object may be compared with the size(s), shape(s), andcolor(s) characteristics of an item category to determine a similaritybetween the object and the item category.

If the object represented in the user provided image cannot beassociated with an item category, the image is sent for manual reviewand categorization, as in 1110. Manual review and categorization mayinclude one or more humans reviewing the user provided image todetermine a category for the object represented in the image. Thehuman(s) may be an employee of the management service, a user of themanagement service, a seller, etc.

If it is determined that the object represented in the image can beassociated with a category, or upon manual categorization, similaritiesbetween the object represented in the user provided image and the imagesof the item catalog associated with the determined category aredetermined, as in 1112. For example, the processed image information(e.g., feature vectors, histogram) from the user provided image may becompared with image information relating to the images corresponding tothe items identified in the item catalog to determine a similaritybetween the images.

Based on the similarities between the user provided image and the storedimages, a probability is determined for the stored image having thehighest similarity to the user provided image, indicating how likely itis that the stored image corresponds to the user provided images, as in1114. The probability may be based on a difference between thedetermined similarity scores. For example, if the highest similarityscore is 95% and the next highest similarity scores are 45% and 34%,there may be a high probability that the stored image having the highestsimilarity score corresponds with the user provided image. Incomparison, if the highest similarity score is 95% and the next highestsimilarity scores are 94% and 93%, even though the images are similar,there is a low probability that the stored image with the highestsimilarity score corresponds to the user provided image because any ofthose images may actually include the item represented in the userprovided image.

Based on the probability score for the stored image with the highestsimilarity, a determination is made as to whether the probabilityexceeds a confidence threshold, as in 1116. The confidence threshold maybe any number, score, or other indicator that must be achieved for theprobability score to exceed the threshold. The confidence threshold maybe different for different images, different users, different times ofday, etc.

If the probability score does not exceed the threshold, the image issent for manual association by one or more humans, as in 1118. In someimplementations, the image, image data, stored images associated withitems in the item catalog corresponding to the same category, and/or thestored images having the highest similarity scores may also be sent tothe one or more humans for manual association. The one or more users maybe employees of the management service, employees of the potentialseller of the item, users of the management service, etc.

If it is determined that the probability exceeds the confidencethreshold, or upon manual association, the user provided image isassociated with the item identified in the item catalog and/or theseller of the item identified in the item catalog, as in 1120. Thisassociation is maintained in the mapping data store by the managementservice.

Based on the association between the user provided image and the itemidentified in the item catalog data store and/or the seller of the item,each time the user provided image is presented to a user, such as when auser requests to view the user provided image, the presentation of theimage will include a purchase control and/or seller information, as in1122. The purchase control, as discussed above, may be selected by theuser to obtain additional information about the item represented in theuser provided image and/or to initiate a purchase of the item. Theseller information identifies a seller of the item represented in theimage. If multiple sellers are associated with the item represented inthe image, the seller information may identify one of the sellers, aseller based on a provided advertising amount for the item, multiplesellers, provide an indication that more than one seller is offering theitem represented in the user provided image for sale, etc. A userrequesting to view the user provided image may be the user that providedthe image, or any other user of the management service.

FIG. 12 illustrates an example purchase request process 1200, accordingto an implementation. The example process 1200 begins upon selection bya user of the purchase control, as in 1202. As discussed above, apurchase control is presented with a user provided image when the userprovided image is determined to include a representation of an itemoffered for sale by a seller.

Upon receiving a selection of a purchase control, the seller is queriedfor current item variant information corresponding to the itemrepresented in the image, as in 1204. As discussed above, in someimplementations, the seller may be queried for item variant informationin response to selection of a purchase control, the seller mayperiodically send item variant information to the management service,and/or the seller may provide updates to item variant information whenan item variant changes.

The example process 1200 also sends to the client device of the user,item details and current item variant information for presentation tothe user, as in 1206. As illustrated and discussed above with respect toFIG. 8, the presentation to the user may include additional views of theitem, current item variant information, purchase details, etc. Likewise,as discussed above, the user may modify and/or select particular itemvariants for the item that may be used to complete a purchase of theitem. For example, the user may select a particular size, color, and/orother variants for an item that may be used in the purchase and/ordelivery of the item.

A determination is then made as to whether a purchase request has beenreceived, as in 1208. For example, a user may select to purchase an itemupon selecting desired variants and providing purchase details (e.g.,delivery destination, credit card information, delivery time). If apurchase request is not received, the example process completes, as in1209. However, if it is determined that a purchase request has beenreceived, the selected item variants, delivery information, and userinformation for the user initiating the purchase are sent to the sellerof the item, as in 1210.

In response to sending the selected item variants, delivery information,and user information to the seller, the example process 1200 receivesfrom the seller a purchase identifier that identifies the purchasetransaction and purchase details (e.g., shipping fee, identificationtag, shipping time), as in 1212.

Based on the user provided information, and the seller provided purchaseinformation, the example process 1200 facilitates purchase of the itembetween the user and the seller, as in 1214. Additional details forfacilitating purchase of an item between a user and a seller of the itemare discussed in further detail below with respect to FIG. 13. Finally,once the purchase has been completed, a purchase confirmation is sent tothe user, as in 1216. The purchase confirmation may be sent in the formof a presentation on the user's client device, an electronic message(“e-mail”), a text message, etc.

FIG. 13 is a block diagram of a purchase process, according to animplementation. As discussed above, the management service 1310 mayfacilitate a purchase of an item between a user 1301 and a seller 1306.In the implementations discussed herein, a user of the managementservice may purchase an item from a seller other than the managementservice without ever leaving the website of the management service. Atthe same time, the seller is able to promote and sell their goods viathe management service, even using images provided by users of themanagement service that are independent of the seller and/or themanagement service.

When a user 1301 selects desired item variants and initiates a purchaseof an item, the management service 1310 receives the purchase requestand the selected item variants. The management service may also maintainin the user profile data store purchase information (e.g., credit card,billing information, and delivery information) for the user, and/or theuser may provide such information as part of the purchase request.

Based on the relationship between the management service and the sellerof the item, payment for the item may be completed differently. In oneimplementation, the seller of the item may maintain a payment accountwith a third party payment processor 1302 that accepts payments forpurchases facilitated by the management service 1310. In such aconfiguration, no purchase details of the user are provided to theseller 1306 and the seller remains the seller of record. When a purchaseis made, the payment is processed by the third party payment processor1302 and made to the seller's account that is maintained by the thirdparty payment processor 1302. In another configuration, the seller maybe their own payment processor. In such a configuration, the user'spurchase details may be provided from the management service 1310 to theseller 1306 and the seller may process payment for the item.

In either configuration, upon receipt by the management service 1310 ofa purchase request from a user 1301, the total cost for the purchase(e.g., price, tax, shipping), the payment token that identifies thepurchase transaction and the seller identifier is sent to the paymentprocessor 1302 (either the third party payment processor, or the paymentprocessor of the seller). The payment processor 1302 processes andconfirms that the payment is authorized and sends back to the managementservice 1310 a payment transaction identifier and an indication that thepayment is authorized.

The management service, upon receiving the payment transactionidentifier, sends the payment transaction identifier to the seller 1306confirming that the purchase has been authorized. The seller, inresponse, may send a purchase confirmation back to the managementservice 1310 confirming that the purchase is complete. Likewise, themanagement service may send a notification to the user confirming thatthe seller has confirmed purchase of the item. When the seller initiatesdelivery of the item, the funds may be retrieved from the paymentprocessor and the transaction completed.

In still another implementation, the management service 1310 may preparea fully configured order that includes the item to be purchased, itemvariant information (e.g., quantity, color, size), shipping information,user information necessary for the seller to complete a sale of the itemto the user (e.g., user information, payment information), and the like.The fully configured order may then be sent directly to the seller 1306.A seller 1306, upon receiving a fully configured order from themanagement service 1310 processes the order and returns to themanagement service 1310 either a purchase confirmation or an errorindicating that the purchase was not completed for one or more reasons(e.g., invalid payment information). The management service 1310 maysend a notification to the user 1301 confirming that the seller hasconfirmed purchase of the item or that there was an error with thepurchase request. If an error occurred, the management service 1310 mayobtain from the user, information needed to resolve the error andprovide that information to the seller 1306 so that the purchase of theitem from the seller can be completed.

FIG. 14 is a pictorial diagram of an illustrative implementation of aserver system, such as the server system 1400 that may be used in theimplementations discussed herein. The server system 1400 may include aprocessor 1401, such as one or more redundant processors, a videodisplay adapter 1402, a disk drive 1404, an input/output interface 1406,a network interface 1408, and a memory 1412. The processor 1401, thevideo display adapter 1402, the disk drive 1404, the input/outputinterface 1406, the network interface 1408, and the memory 1412 may becommunicatively coupled to each other by a communication bus 1411.

The video display adapter 1402 provides display signals to a localdisplay (not shown in FIG. 14) permitting an operator of the serversystem 1400 to monitor and configure operation of the server system1400. The input/output interface 1406 likewise communicates withexternal input/output devices not shown in FIG. 14, such as a mouse,keyboard, scanner, or other input and output devices that can beoperated by an operator of the server system 1400. The network interface1408 includes hardware, software, or any combination thereof, tocommunicate with other computing devices. For example, the networkinterface 1408 may be configured to provide communications between theserver system 1400 and other computing devices, such as the clientdevice 104, via the network 108, as shown in FIG. 1.

The memory 1412 generally comprises random access memory (RAM),read-only memory (ROM), flash memory, and/or other volatile or permanentmemory. The memory 1412 is shown storing an operating system 1414 forcontrolling the operation of the server system 1400. A binaryinput/output system (BIOS) 1416 for controlling the low-level operationof the server system 1400 is also stored in the memory 1412.

The memory 1412 additionally stores program code and data for providingnetwork services that allow client devices and sellers to exchangeinformation and data files with the server system 1400 and/or themanagement service 1410. Accordingly, the memory 1412 may store abrowser application 1418. The browser application 1418 comprisescomputer executable instructions, that, when executed by the processor1401, generate or otherwise obtain configurable markup documents such asWeb pages. The browser application 1418 communicates with a data storemanager application 1420 to facilitate data exchange and mapping betweenthe mappings data store 1411, the image data store 1413, the itemcatalog data store 1415, and/or the user profile data store 1417, clientdevices, such as the client device 104 shown in FIG. 1, and/or sellers,such as the sellers 106 shown in FIG. 1.

As used herein, the term “data store” refers to any device orcombination of devices capable of storing, accessing and retrievingdata, which may include any combination and number of data servers,databases, data storage devices and data storage media, in any standard,distributed or clustered environment. The server system 1400 can includeany appropriate hardware and software for integrating with the datastores 1411-1417 as needed to execute aspects of one or moreapplications for the client device, the sellers and/or the managementservice 1410. The server system 1400 provides access control services incooperation with the data stores 1411-1417 and is able to generatecontent such as text, graphics, audio, video and/or images to betransferred to a client device and/or sellers.

The data stores 1411-1417 can include several separate data tables,databases or other data storage mechanisms and media for storing datarelating to a particular aspect. For example, the data stores 1411-1417illustrated include mechanisms for storing images, user information,mappings and item catalogs from sellers of items, which can be used togenerate and deliver content to client devices and/or sellers (e.g.,user provided images and purchase controls) and control actions to beperformed.

It should be understood that there can be many other aspects that may bestored in the data stores 1411-1417, such as access rights information,preferred sellers, etc., which can be stored in any of the above listedmechanisms as appropriate or in additional mechanisms of any of the datastores 1411-1417. The data stores 1411-1417 are operable, through logicassociated therewith, to receive instructions from the server system1400 and obtain, update or otherwise process data in response thereto.

The memory 1412 may also include the management service 1410, discussedabove. The management service 1410 may be executable by the processor1401 to implement one or more of the functions of the server system1400. In one implementation, the management service 1410 may representinstructions embodied in one or more software programs stored in thememory 1412. In another implementation, the management service 1410 canrepresent hardware, software instructions, or a combination thereof.

The server system 1400, in one implementation, is a distributedenvironment utilizing several computer systems and components that areinterconnected via communication links, using one or more computernetworks or direct connections. However, it will be appreciated by thoseof ordinary skill in the art that such a system could operate equallywell in a system having fewer or a greater number of components than areillustrated in FIG. 14. Thus, the depiction in FIG. 14 should be takenas being illustrative in nature and not limiting to the scope of thedisclosure.

Although the subject matter has been described in language specific tostructural features and/or methodological acts, it is to be understoodthat the subject matter defined in the appended claims is notnecessarily limited to the specific features or acts described. Rather,the specific features and acts are disclosed as exemplary forms ofimplementing the claims.
